I'm not sure if you noticed because it's very subtle, but I purposely break "the fourth wall" on several different occasions. When the NSA agent (Ron) delivers the line, "it is YOU who enforces the grand illusion", right as he says the word "you", he looks dead into the camera. The second time it happens, is when we get a break from the conversation, and suddenly we're viewing the two of them in the same shot, from a distance, but the shot is blurred. In my mind, that symbolizes us (the viewer) watching these two men, but not really having a clear understanding of what's going on. The last and final time the fourth wall is broken, is at the very end, when the agent is finally taken away, the very last shot is the prisoner looking at the camera, as if he knows something that we don't. And maybe he does, or maybe he doesn't, that's for you to decide. But the key point is, he could "better the world", or he could do exactly what the agent predicts, and over time become an agent himself.
Another thing to spot, is when the agent says, "The world's full of recycled ideas. There've been people just like you, that've sat in that chair just like you." That's a hint that says, him and whatever agency he's working for, have wronged a lot of people... including the people that work right under his nose, hence why his own men turn on him. Think about that one scene in Fight Club, when Edward Norton's character takes that rich bastard into the bathroom and tells him, "Look, the people you are after are the people you depend on. We cook your meals, we haul your trash, we connect your calls, we drive your ambulances. We guard you while you sleep. Do not... FUCK with us." It's kind of like that.
What the NSA agent fails to understand, is that he himself has fallen to the same system he's blabbering on about. He talks like he's God, but at the end we figure out that's not really case (lol), because he is also a prisoner.
